SPECIFICATIONforming part of Letters Patent No. 653,308, dated July 10,1900. .Application tiled October 19,1899. Serial No. 734,084. (Nomodel.)

To a/ZZ whom, t may concern:

Be it known that I, EDWIN MORSE, a citi-y zen of the United States,residing at Stockton, in the county of Jo Daviess and State of Illinois,have invented certain new and useful Improvements in Nut-Locks and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and tothe letters of referencemarked thereon.

The present invention has relation to that class of nut and bolt locksin which the nut is provided with a slotted tubular extension upon itsouter side to receive a transverse key which extends through the sameand through a hole in the screw-threaded end of the bolt.

Itis the purpose of the invention to improve the construction of theabove class of locknuts, whereby the key is more securely held in placewithout the necessity of the employment of the usual spring-keys orother devices heretofore used for preventing the key from beingaccidentally removed from the bolt; and the invention consists in alocknut constructed substantially as shown in the drawings andhereinafter described and claimed.

Figure 1 of the drawings is a perspective view of a nut-lock constructedin accordance with my invention; Fig. 2, a side elevation thereof,partlyin section; Fig. 3, an end sectional view; Fig. 4, a similar viewshowing the nut turned to bring the locking-shoulder of the key underthe stay-bar of the nut to prevent said key from being withdrawn.

In the accompanying drawings, A. represents a screw-threaded bolt of theusual construction, having a hole a near its end and extending at rightangles to its axis. The screwthreaded nut B has an extension upon itsouter side which comprises the four stay-bars O, with openings betweenthem, as shown at b, which bars and openings continue throughout thelength of the extension and are joined by a head D. The inner sideof thebars C are screw-threaded, as is also the opening through the head D,with which may engage the screw-threads of the bolt A. The elongatedopenings in the extension require no nicety of adjustment to bring theopenings on line with the opening or hole in the bolt, so that the keymay be inserted, asin the perforated extensions heretofore in use.

It is preferable that the nut and the extension be integral and theopenings of the eXtension of such Width that will readily admit the keyE. The head D, which joins the bars C together at 4their outer ends, maybe of any suitable thickness or depth, and the screwthreaded openingtherein is of a size to correspond with the diameter of the screw-bolt.The bars C may be of any desirable thickness necessary to give therequired strength Ato the extension.

The nut can be screwed up as tightly as possible against the objectthrough which the bolt passes and held firmly and stationary in that.position by the employment of the slotted extension, thereby preventingthe nut from rattling or working loose.

The key E is formed with a locking outer shoulder c, so that when thenut is turned to the position as indicated in Fig. 4 of the drawings theshoulder will be on line under one of the stay-bars O. This willsecurely lock the key ,and prevent it from being accidentally withdrawn,this feature of the invention being considered of material importance,as it dispenses with y the usual spring-key or any additional meansnecessary to hold the key in engagement with the bolt. If desired, asecond inner shoulder CZ may be formed on the key to adapt the same foruse in a double nut-lock, although this may be dispensed with, if foundpreferable, as the one shoulder will be sufticient. l

It should be noticed that the bars O are threaded throughout theirlength, thereby giving a iirmer hold to the bolt and increasing thestrength of the nut and rendering the parts more rigid, this beingconsidered a material advantage.

Hav-ing now fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. A nut-lock comprisinga screw-threaded bolt having a transversekey-opening, a nut havinga plurality of stay-bars and a head interiorlyscrewthreaded, and a key constructed with a head adapted to occupy aposition between two stay-bars, and With a shoulder beneath the headadapted to engage IOO the inner side of a stay-bar to prevent the thekey when seated, and with an inner shoul Withdrawal of the key whenseated.

2. A nut-look comprisinga screw-threaded bolt having a transversekey-opening, a nut 5 having a plurality of stay-bars and a headinteriorly screw-threaded, and. a key constructed with a head adapted tooccupy a po'- sition between two stay-bars, with an inner end adapted tooccupy a position between the 1o opposite stay-bars, Wit-h an outershoulder adapted to engage the inner side of the adjav cent stay-bar andprevent the Withdrawal of der adapted to engage the inner side of theopposite stay-bair and limit lthe inner movement of the key When seated.

In testimony that I elairn the above I have hereunto subscribed my namein the presence of two Witnesses.
